This gall comes in two forms: with spines (and is unmistakable then) but also completely smooth (and then without breeding undistinguishable from Diplolepis eglanteriae). Univoltine; hibernation and pupation in the gall.

notes

Hans Jonkman found in the Roggebotbos (province of Flevoland), next to the typical D. nervosa galls also numerous aberrant galls. They belonged to the D. eglanteriae type (without large spines) but differed in being covered with glandular hairs, that often were connected by low ridges. In older galls the glandular hairs had been transformed into low warts.
